Hi Everyone. Im finally getting back to my robot project and installing the EZB V3. I am using a Sabertooth 2x25 V2.00 to drive two 24 volt motors and want to ultimately use an iPad to control my bot and steer with differential control of the two motors. I will be adding a bunch of other devices and functions but Im starting with the drive.

Can anyone help on the best mode (i.e. dip switch settings) to set the Sabertooth? Not sure if I should have switch 4 down (independent mode) or up (mixed mode). Also, Im confused about how best to connect to the EZB. I was thinking Id be using digital ports 00 and 01 but not sure. Then there is dip switch 1 which sets analog mode if down. I cant help thinking im in a bit over my head here.

If I use the two digital ports should dip switch 1 be up? (and 4 down?)? Im so confused.

Any help or links to tutorials would be greatly appreciated.

I have found a few conversations, tutorials and activities that may help with your question. Take a look at these links. I've sorted them by what I believe to be most relevant but that is not always the case as I'm still learning.

Also, consider reviewing the Learn section for informative lessons and activities. Check it out!


Put it in simple serial mode and use 1 digital port from the EZ-B.

Have a read of this topic for some more info. Here's another one.


Set 1, 3 and 6 to up or "on" the rest down... This is serial mode. The baud rate will be 38400....

As Rich stated you use only one ezb port and 2 wires... One wire to ground or 0v on the sabertooth and the other wire from the ezb signal/data pin to S1 on the sabertooth....


Awesome. Thanks so much guys! Smile
